I have never understood the mass paranoia over laptop webcams — which have in-use indicator lights, which I’ve seen no evidence can be circumvented on Macs from the last decade — and the complete lack of similar paranoia over microphones, which cannot be blocked by a piece of tape and which have no in-use indicator lights. And I don’t see anyone taping over the cameras on their phones.

Gruber commented on Joanna Stern’s column for the Wall Street Journal; a very good article, which has the merits of existing and giving precise, documented answers to this question. But indeed, the whole piece is feeding the paranoia over laptop webcams.

If I had to chose a way to be hacked, between what my open laptop webcam sees, what is displayed on my screen, what the microphone can hear, what words (and passwords) I type on the keyboard, and what websites I visit, I would chose the laptop webcam.

I see more people with a piece of tape on their webcam than using a password manager. I see more people using fishy Chrome extensions with too much access than I see people using a proper 2-factor authentication or keep their devices updated.

In the end it is about feeling safer, and hardware’s sense of security (locks on the door, blinds on the windows, piece of tape on the webcam) is much easier to control than software’s (a complex and unique password for each app, encrypted messaging, 2-factor authentication, etc.) Why those basic things are not more often taught in schools is beyond me.
